问题

有没有办法将字符串用作函数名并调用它？

我有一个将字符串映射到函数名的映射表
stuff := map[string]string{'keyword','function'}

当使用keyword时，我想用两个参数调用function
stuff['keyword'](arg1,arg2)

但是它给我报错：

无法调用非函数键（类型为字符串）

有没有办法保持我的字符串到字符串映射，并且仍然实现这个功能？

英文:

Is theere a way to use a string as a function name and call it?

I have a map of strings to function names
stuff := map[string]string{'keyword','function'}

and when the keyword is used, i want to call function with 2 arguments
stuff['keyword'](arg1,arg2)

But it gives me this error:

cannot call non-function key (type string)

Is there a way to keep my string to string map and still achieve this?

你正在使用的地图在语法上是无效的。你可能想要像这样的东西：

stuff := map[string]func(string, string)

然后，你可以使用字符串键从地图中提取一个函数并调用它：

stuff["keyword"]("foo", "goo")

英文:

The map you're using isn't syntactically valid. You probably want something like this:

stuff := map[string]func(string, string)

You would then be able to use your string key to pull out a function from the map and call it:

stuff[&quot;keyword&quot;](&quot;foo&quot;, &quot;goo&quot;)
